DUMPING OR UNPACKING TRUCK.

Specification of Letters Patent.

Patented Aug. 8, 1911.

To all whom it may concern:

Be it known that I, WILLIAM VmTUs ELLIS, a citizen of the United States,residing at I-Iuntingdon, in the county of Huntingdon and State ofPennsylvania, have invented certain new and useful Improvements inDumping or Unpacking Trucks, of which the following is a specification.

My invention relates to dumping or un packing trucks which are designedto receive the contents of a case of merchandise by being inverted uponthe top of such open case, and then to receive such contents by tippingthe case over so that the said contents will freely pass to the floor ofthe truck. Such a truck is illustrated in my Patent No. 9453,0413, datedFeb. 1, 1910.

The particular invention forming the subject matter of this presentapplication will be found useful in connection with the truckillustrated in my said patent, and has for its object to provideportable lifting and moving means for the said truck, whereby itsusefulness is increased.

I have illustrated a desirable form in which my invention may beembodied in the accompanying drawings, wherein Figure 1 is an elevationof the said truck illustrating my invention applied thereto; Fig. 2 is asection on the line 22 of Fig. 1 looking to the left. Fig. 3 is a detailpartly in section illustrating the position assumed by the parts whenthe lifting and moving device is first applied; Fig. A is a detail frontview of the said lifting and moving device partly broken away. Figs. 5and 5 are detail side and end views of the axle, and Figs. 6 and 6 aresimilar cletail views of the locking dog.

In carrying my invention into effect, I have provided the truck of myformer patent with a rear axle which may be freely turned horizontally,and in connection therewith I make use of a separable frame having meansfor engaging the said axle and carrying a single wheel and a handlewhereby the axle-engaging means are in serted in place and upon apressure downward of the handle, the wheel is brought into place underthe truck and the same is lifted and easily propelled, the single wheelacting in connection with the revolving axle to direct the movement ofthe truck to any desired place.

In the particular form in which my invention is illustrated in theaccompanying drawing, the lifting and propelling means are shown asconsistingof two plates A which are similar in all respects, and whichmay be made of any desired material, such as malleable cast iron, whichI have found well adapted to the purpose. Each of these plates has ahandle post a and a supporting post a A convenient way of supporting thehandle B, I find to be by attaching the said handle to a plate (1. whichconnects the handle posts together. A similar connection a between thesaid plates A serves as a support or axle for the wheel 0. Thesupporting posts a are each forked at their upper ends at a formingbearings adapted to receive trunnions for a purpose presently to bedescribed. Each of these posts is likewise provided on its forward sidewith a notch a and the material of the plate above said notch ispreferably extended as at a forming a locking shoulder.

Upon the rear under side of the dumping truck illustrated in my saidpatent I provide means for supporting the bearing, as for instance, byan angle iron D. Depending from this angle iron and attached thereto bysuit able bolts, is a rectangular frame cl which supports a shaft E. Thesaid shaft has an upwardly projecting stem e which passes through theframe [Z and may enter a hole in the angle iron D for the purpose ofholding the said stem perpendicular. Suitable means may be employed forholding the shaft in place, as for instance, a pin 6 which passesthrough the stem 6 above the frame (Z. It will be perceived that theforegoing construction permits the said shaft to freely turnhorizontally. I have provided means upon the said shaft for receivingthe bifurcated ends of the supporting posts a consisting of a reducedshoulder 6 upon each side forming trunnions which have bearings in theforked ends a of the said posts a Suitable means may be provided forholding the lifting device and the dump ing truck together, as forinstance, by a swinging bail-shaped locking dog F which has its endsturned into loops, and the said loops are received one upon each reducedend 6 of the axle E.

It will be observed that the handle post and handle and the supportingpost are at an angle to each other in the case shown,

this angle being approximately 45. The handle, however, I prefer to bendat Z) so as to increase such angle from the point of the bend outward.The said handle and supporting posts, however, may be otherwise relatedto each other.

In using my device the bifurcated ends of the supporting posts will becaused to embrace their bearings upon the shaft substantially asillustrated in Fig. 3, whereupon downward pressure being exerted uponthe handle the truck will be raised and the wheel 0 will be caused topass under the rear portion of the truck and the dog 1* will swing intothe slot at and behind the shoulder a, and will tend to prevent thetruck tippingforward. The parts being in this position the truck may beeasily propelled to any desired locality upon the forward wheels whichrest upon the ground. The rear of the truck will then be lifted from theground and will be supported by the wheel C which, owing to the turningof the shaft IE, will cause the truck to be easily guided to any desiredpoint. Should it be desired to leave the lifting device in position, thetruck may simply be lowered and permitted to rest upon its bottom frame,whereupon the wheel will remain in position as the weight of the handlewill keep the lifting device from passing out of connect-ion with therear end of the truck. The lifting device might easily be locked inforward position by causing the wheel to pass in front of the axle andproviding a stop 011 the frame to engage the supporting post and therebylock the device in position with the truck lifted.

Although I have described with some particularity the mechanical detailsof construction of my lifting device, it is not therefrom to be assumedthat I regard my invention as limited in its practical embodiment tosuch details. The essential details of my invention may be changed andequivalent devices substituted within the limits of the appended claims.

The illustrated means for causing wheel C to turn easily, embracingshaft E, are practicable means for accomplishing the purpose, but otherand equivalent means might be employed and I do not regard my inventionas limited to the employment of such means illustrated.

What I claim is 2- 1. In an unpacking truck, hand-operated means forpropelling and guiding the truck and for lifting one end thereof,comprising a frame, a single wheel mounted therein, a handle attached tosaid frame at an angle which permits it to extend upwardly andrearwardly when the frame is in supporting position, and adapted tooperate said frame for lifting and to guide and propel the same, aseparable swivel connection between the frame and the truck whereby theframe may be turned relatively to the truck, permitting the frame to befreely separated from the truck, the said swivel connection adapted tobe connected before the truck is raised and to lift one end of the truckwhen the handle is depressed and swing the frame to supporting positionbeneath the truck, said frame adapted to be freely disconnected from thetruck by raising the handle, where upon the truck will be lowered.
